Abstract

Ein insbesonders zur Messung des Innendruckes von Einspritzleitungen von Dieselmotoren verwendeter Sensor weist zwei Gehäuseteile (2, 2') auf, die über ein Gelenk verbunden und mit einer Spannvorrichtung (3, 4) auf die Leitung (1) aufklemmbar sind. Die Spannvorrichtung (3, 4) befindet sich zur leichten und insbesonders auch einhändigen Anbringung des Sensors in jedem Zustand des Öffnens und Schließens im gleichen dem Gelenk zugewandten Sektor auf einer Seite des Rohraußenbereiches. Der Anschlußstecker (5) für die Ableitung der Meßsignale ist bevorzugt in das entsprechend ausgebildete Gelenk einsteckbar und dort verriegelbar.

Figure 00000001
A sensor used in particular for measuring the internal pressure of injection lines of diesel engines has two housing parts (2, 2 ') which are connected via a joint and can be clamped onto the line (1) with a tensioning device (3, 4). The clamping device (3, 4) is for easy and in particular one-handed attachment of the sensor in every state of opening and closing in the same sector facing the joint on one side of the outer tube area. The connector (5) for deriving the measurement signals can preferably be inserted into the correspondingly designed joint and locked there.
